I noticed, that this forum is based on phpBB. We had serious spambot problems at another phpBB forum until we installed the
Anti Bot Question Mod. Since we use that, no single spam entry anymore.
This plugin is highly configurable. In addition to the standard captcha it presents a configurable question to the person who wants to register. It should be a simple question, that can be answered by anybody (except spambots), so you will not lose any customer. Installation and configuration shouldn't take longer than 1 hour for an experienced admin, but will save a lot of time for the moderators in the future
